91/16 is good, stop worrying about unimportant things. The extra speed that you'll never get in practice makes no practical difference.
Yep, I do agree with that.
My interest was more about understanding why it is what it is. I appreciate the extra speed will not be noticeable.
I am tech enough to be dangerous, but not useful.
If it were not for the Chorus technician saying you should be getting very much just over or under 100/20 (ie implying that the providers could ensure a miniumum level of speed right at the point of your ONT/router) I would not have bothered any further.
It was interesting that same technician said they use the same Speedtest site we all do for their testing.
